Hi, I have a local PostGIS database with a small extract of the planet loaded. I also have a bunch of polygons created as shapefiles with QuantumGIS. Mapnic does a fantastic job of rendering maps showing the area of the shapefiles. What I would like to to is extract a list of names from all the roads that come from the PostGIS database that are within the shapefile polygon. Is that possible? After that, I would like to extract the centre point of the roads as well.
The reason is that I want to make some small maps where every road is named. The standard text symbolizer works OK to a point, but leaves many small streets un-labeled. For the moment, I have created extra line and point shapefiles that hold the names and arrows so that I can manually place the labels, but it would be better to have the system create a list of roads, and then automatically place the names and leaders to the centre of the roads. Does that make sense? To that end, I will also need to know if it is possible to manually place text on a map with Python. -- Philip Stubbs _______________________________________________ Mapnik-users mailing list [email protected] https://lists.berlios.de/mailman/listinfo/mapnik-users
